3 Description

The TL331B-Q1 and TL391B-Q1 devices are the

next generation versions of the industry-standard

TL331-Q1 comparator. These next generation

devices provide outstanding value for cost-sensitive

applications, with features including lower offset

voltage, higher supply voltage capability, lower supply

current, lower input bias current, lower propagation

delay, dedicated ESD protection cells with improved

negative input voltage handling. The TL331B-Q1

can drop-in replace both the TL331-Q1 I and

Q versions. The TL391B-Q1 provides an alternate

pinout of the TL331B-Q1. The TL331E-Q1 extends

the temp range up to 150ºC, meeting AEC-Q100

Grade 0 temperature requirements.

This device consists of a single voltage comparator

designed to operate from a single power supply

over a wide range of voltages. Operation from dual

supplies also is possible if the difference between the

two supplies is 2V to 36V and VCC is at least 1.5V

more positive than the input common-mode voltage.

Current drain is independent of the supply voltage. To

achieve wired-AND relationships, one can connect the

output to other open-collector outputs.
